Hello all,
I have done many and many test to use the 1:n mapping with a Map collection but i
haven't find the solution.
I have
public class Client {
private Map contacts = null;
public Client() {
this.contacts = new HashMap();
}
}
<!-- Definitions for com.mps.safari.commun.Client -->
<class-descriptor class="com.mps.safari.commun.Client" table="client">
<field-descriptor id="1" name="id" column="CLIENT_ID" jdbc-type="BIGINT"
primarykey="true" autoincrement="true"/>
<field-descriptor id="2" name="code" column="CODE" jdbc-type="BIGINT"/>
<collection-descriptor name="contacts"
element-class-ref="com.mps.safari.commun.Contact" collection-
class="org.apache.ojb.odmg.collections.DMapImpl" auto-update="true" auto-delete="true">
<inverse-foreignkey field-ref="codeClient"/>
</collection-descriptor>
</class-descriptor>
And i have the following error :
[org.apache.ojb.broker.accesslayer.RsIterator] ERROR:
